Previous Comments: ------------------------------------------------------------------------ [2006-05-31 08:43:58] [EMAIL PROTECTED] Please, fix your code, there is nothing wrong neither with mcrypt library nor with PHP. ------------------------------------------------------------------------ [2006-05-31 07:44:46] coditza at cluj dot astral dot ro Indeed, your sugestion fixed the thing, but that's just a work around. I added some debuing bits and here are 2 outputs: string: 12345678qwertyui12345678g 0) Encoding: 12345678 - 7e0dc5b2ff23aca1 1) Encoding: qwertyui - eb3b6b54025c6347 2) Encoding: 12345678 - f258e8a6ab3003af 3) Encoding: g - 20d274568051c4e6 4) Encoding: - 43f92ddf945e42fc string lenght is 25, ceil(25/8) = 4, the for loop you sugested is "processing" an aditional empty part of the string. Again, this is a workaround, not a fix/user error. Please fix the library or point out in the docs that for a succesfull crypt you need to use this thinghy. Thanks ------------------------------------------------------------------------ [2006-05-30 23:35:29] [EMAIL PROTECTED] Change for($i=0;$i<$max;$i++) { to for($i=0;$i<=$max;$i++) { Not PHP problem, just a user error. ------------------------------------------------------------------------ [2006-05-29 13:07:08] coditza at cluj dot astral dot ro The example is for freebsd 6.0 actually, but the beavior is the same both on windows (with php4) and on freebsd (with php5) ------------------------------------------------------------------------ [2006-05-25 23:49:00] coditza at cluj dot astral dot ro Description: ------------ If the lenght of the encoded string is a multiple of chipher block size, the last blocksize part of the chipher is lost at decoding. Reproduce code: --------------- Use the script at: http://www.coada.net/develop/crypt.phps to produce an encoded file, then, from shell: openssl bf-cbc -in out.dat -out out.dec -K 000102030405060708090a0b0c0d0e0f -iv 0102030405060708 -d and cat out.dec Expected result: ---------------- [EMAIL PROTECTED] [EMAIL PROTECTED] Actual result: -------------- bad decrypt 31976:error:06065064:digital envelope routines:EVP_DecryptFinal:bad decrypt:/usr/src/secure/lib/libcrypto/../../../crypto/openssl/crypto/evp/evp_enc.c:450: [EMAIL PROTECTED] cat out.dec [EMAIL PROTECTED] ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37595&edit=1
